ABSTRACT:
A process for separating and condensing at least one selected organic liquid from a feed comprising a mixture thereof in the state of one phase or two phases which comprises conducting ultrafiltration by using a polymeric porous membrane having a mean pore size(2ra ) of at least 10.sup.-6 cm and a porosity (Pr) of at least 50% under the conditions that the effective pressure gradient (.DELTA.P/d) loaded on the polymeric porous membrane satisfies the following equations:
